The six kingdoms in the Domain of Life are Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria. They are ordered according to characteristics that determine the degree of complexity of their cells, body structure, and method of nutrition.
The most complex kingdom is Animalia, which is comprised of multicellular organisms that obtain nutrition by ingesting other organisms (remember the food chain). Plantae are multicellular photosynthetic organisms, which produce their own food from the sun’s energy.
Fungi are multicellular, most of which obtain nutrition by breaking down and absorbing organic materials from the environment. Protista is a varied kingdom consisting of unicellular organisms that use a variety of methods of nutrition.
Archaea are unicellular organisms that are adapted to living in extreme environments such as hot springs and salt lakes. Bacteria are unicellular organisms that use diverse methods of nutrition, encompassing everything from photosynthesis to parasitism.
What are the 6 kingdoms of life describe each kingdom?
The 6 kingdoms of life are the main taxonomic categories at the highest level of classification, classifying all living organisms based on certain characteristics. The 6 kingdoms are Animalia (animals), Plantae (plants), Fungi (fungi and mushrooms), Protista (protists, single-celled eukaryotes), Archaebacteria (sometimes called extremophiles, prokaryotes), and Eubacteria (also called true bacteria, prokaryotes).
Animalia is composed of multicellular organisms that ingest their food and are able to move about in their environment. They are capable of sexual reproduction, and their cells are typically organized into tissues and organs.
Plantae is composed of multicellular organisms that produce their own food through photosynthesis. They generally take their nutrients from the soil, and most of their cells are organized into tissues and organs.
Fungi are eukaryotic, multicellular organisms that are decomposers and feed on living and dead matter. They typically absorb their nutrients from the environment.
Protista are unicellular and multicellular eukaryotes that feed on living and dead matter. These vary in cell structure and may be autotrophic (producing their own food) or heterotrophic (ingesting their food).
Archaebacteria are prokaryotes, bacteria with no nucleus or other organelles enclosed in membranes. These are found in extreme environments such as hot springs and deep-sea vents, and have been important to early life on Earth.
Eubacteria are also prokaryotes and the most common form of bacteria on Earth. They are found in almost all environments, and are important to the production of food and energy.
